Kevin Lubick e3b013047d Experiment with turning CPUs off during perf
Perf was nice and flat after https://skia-review.googlesource.com/c/skia/+/83240
but there was a 4-5x slowdown on the benchmarks themselves,
indicating that perhaps we were running nanobench on the
LITTLE cores (now on powersave) instead of the big cores we
thought (which were recently scaled down).

This experiment will show us FOR CERTAIN that we are
running on core 0 or 1 which is at .6 max frequency.

We expect to see a speedup from the previous results.

This is leading to turning of CPUs we don't need
to make sure nanobench is running on the ones we expect.
